CAN-CLOSURE.

Specification of Letters Patent. 4-, 7'

Application filed May 2. 1900; Serial No. 314,328.

Patented Feb. 5. 1907.

To all whom it may concern:

Be it ,known that I, ALEXANDER L. CA- PBINI, a citizen of the UnitedStates of America, residingat Pittsburg, in the county of Allegheny andState of iennsylvania, have invented certain new and useful Improvementsin Can-Closures, of which the tollowis a specification, reference beinghad therein to the accompanying drawings.

This invention relates to can-closures and its primary object is toprovide a can with a closure of novel construction adapted to be quicklyopened by means of any convenient tool or punching device.

A further object of the invention is to provide a can-closure soconstructed that when the same is opened to permit the contents of thecan to be poured therefrom a convenient pouring-spout is ready for use,said spout' forming a part of or an attachment to the closure proper.

-The invention comprises an internallythreaded cap or socket having anintegral diaphragm, the under surface of which is formed with an annularcut or indentation in alinement with the threaded walls of the cap toweaken the diaphragm to adapt the same to be readily disconnected fromthe remainder of the cap or socket by any suitable im-- plement,preferably of a dull or blunt form.

The invention also includes, in combination with the cap or socket, asuitably-shaped pouring-spout detachably secured to the cap, and a plugor stopper adapted to be removably fitted within said spout, and alsoadapted to be employed as the means for detaching the weakened diaphragmof the cap.

The construction of the improvement will be fully described hereinafter.in connection with the accompanying drawings, which form a part of thisspecification, and its novel features will be particularly pointed outin the appended claim.

In the drawings, Figure 1 is a vertical section of the upper end of acan with my improved closure applied thereto. Fig. 2 is a centralvertical section of the pouring-spout of the device. Fig. 3 is a topplan view of the spout. Fig. 41s a transverse section of a gasket orpacking interposed between the s out and cap. Fig. 5 is a sectional viewof the plug or stopper. Fig. 6 is a view in pers ective of thepacking-gasket. Fig. 7 1s a etail sectional view of the cap orclosuresocket, and Fig. 8 is a bottom plan .view of the cap.

The reference-numeral 1 designates a can of sheet metal, the top 2 ofwhich is formed with a circular opening 3. The-metal surrounding thisopening 3 is bent. downwardly to provide an annular countersunk flange4, uponwhich reststhe flange or base portion 5 of a hollow cap 6. Theinner surface of the cap is screw-threaded for the attachment thereto ofthepouring-spout, and the lower end of the opening in the cap or socket6 is closed by a diaphragm 7, partiall severed from-the flange or baseof the cap y an annular cut or indentation 8. The diaphragm is thusconnected to the cap by a very thin section of metal only, adapting itto be readily severed from the cap by the slight punching blow of asuitable implement, preferabl of a blunt form, as hereinafterexplainekii The flange 5 of the cap is-soldered-to the top of the can,'as shown in Fig. 1.

The spout consists of a funnel-shaped bod portion 11, having apouring-lip 12 and wit an externally-threaded tubular lower terminal 9and an intermediate flange 10, the threaded terminal adapted to engagethe threaded cap 6.

To prevent leakage, I interpose a yielding gasket 13 between the flan e10 of the 5 out and the upper end of the c osure-cap. t is necessary .toprovide a removable stop er adapted to fit within the spout, and for tpurpose I preferably employ a stopper of the iorm shown in the drawings,comprising a plug 14 and a handle 15, an annular stop-flange 16surrounding the upper end of the stopper to limit its inward movement.This form of stopper not only serves the purpose of a removable closureto the spout, but it is also well adapted for use as a punch orimplement to sever the-diaphragm. Cans will usually be shipped with theweakened portion 7 in-.

tact an with the spout and its plug and gas ket shipped separately, andbefore the spout is applied the weakened portion 7 is driven inwardly bythe plug 14 15, as before stated. The spout is then screwed intoposition in the cap and the plug inserted in its mouth, as shown in Fig.1.

It will be observed that the severable and weakened diaphragm is formedintegral with the cap or socket and that the device as a whole providesa secure closure for cans during trans ortation. or storage, while theplug 14 15 or ns a convenient removable stolpper for the can when inuse.

vmg fully described my invention, what ICC I claim as new, and desire tosecure by Let- 1 portion, and a removable ters Patent, is

The combination with a can having an opening in'its top surrounded by anannular countersunk flange, of a closure comprising a fianged cap orsocket internally threaded, and having an integral diaphragm-partlysevered from-the lar weakening cut or indentation in salinement with thevertical-walls of the cap, a spout having an externally-threaded lowerend to fit the socket, a funnel-shaped body body of the cap byan'annuplug or stopper fit v ting within the spout and adapted to beemployed as a means for detaching the weakened dia hragm from the capprior to the insertion o the threaded s out. p i In testimony whereofaffix my signature inthe presence of twowitnesses.
